Dunno if this has been asked before but here goes.
I've normally bought bac water from a pal,but recently i've had a bit of a chew getting it.
Looked on the net,and apparently,it's just as easy to make your own.
Not really wanting to be told it's cheap enough,is your enviroment sterile etc,all i'm
interested in knowing is,(bearing in mind,the solution ratio is 99.1 water and 0.9 benzyl alcohol)
getting the mix slightly wrong,ie;99.0%water,and 0.1% benzyl going to make much difference?
Looked at it on wiki,and it appears to be pretty safe stuff,and not high toxicity.
